ppmtobmp - convert a portable pixmap into a BMP file
ppmtobmp
[-windows] [-os2] [-bpp=bits_per_pixel] [ppmfile]
Reads a portable
pixmap as input. Produces a Microsoft Windows or OS/2 BMP file as output.
All options can be abbreviated to their shortest unique prefix
and you can use a double dash in place of the single dash, GNU-style.
- -windows
- Tells the program to produce a Microsoft Windows BMP file. (This is the
default.)
- -os2
- Tells the program to produce an OS/2 BMP file. (Before August
2000, this was the default).
- -bpp
- This determines how many bits per pixel
you want the BMP file to contain. Only 1, 4, 8, and 24 are possible. By
default, ppmtobmp chooses the smallest number with which it can represent
all the colors in the input image. If you specify a number too small to
represent all the colors in the input image, ppmtobmp tells you and terminates.
You can use ppmquant or ppmdither to reduce the number of colors in the
image.
To get a faithful reproduction of the input image, the maxval
of the input image must be 255. If it is something else, ppmtobmp the
colors in the BMP file may be slightly different from the colors in the
input.
Windows icons are not BMP files. Use ppmtowinicon to create those.
